GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

2015 Cadillac ATS Coupe

Cadillac has become a very, very different company since the dawn of the new millenium. Its turn-of-the-century lineup, consisting of staid offerings like the Seville, DeVille and Eldorado, represented the Old Cadillac. These cars were plagued with Old GM quality issues and catered to a more elderly audience. Since the company's Art and Science design language arrived, though, we've seen Cadillac flesh out its lineup in a big way, introducing notable and (so far) enduring products, like the the CTS, SRX and most recently, the ATS.
With the CTS tackling the 5 Series segment and the SRX duking it out with the Lexus RX and its classmates, the ATS has been left with the tough task of battling the BMW 3 Series, Audi A4 and Mercedes-Benz C-Class, among others. Critically, at least, it has excelled in this role, but it's still working on finding its feet sales-wise. On paper, broadening the model range by adding a two-door personal luxury coupe could help.
After a week with the ATS Coupe, though, we've found a car that, while retaining the standard model's excellent driving character, doesn't quite offer enough visual excitement to stand up to other cars in its segment.

2020 Cadillac CT4-V, CT5-V revealed, less powerful than predecessors

Expectations have reached stratospheric heights for the 2020 Cadillac CT4-V and 2020 Cadillac CT5-V, and for good reason: Their ATS-V and CTS-V predecessors were potent sports sedans with gobs of power and handling and braking to match. Now the new sedans have been revealed, and they're not what we expected. They each lose two cylinders compared with the other vehicles, and on paper, they don't look as capable. But we do have hope that these won't be the end-all, be-all performance Cadillacs. First, let's look at the cars. The CT4-V will be the base of the V brand, and it's our first look at the small luxury sedan. It has a roofline and window treatment more like past Cadillacs, eschewing the C-pillar garnish of the CT5. It also naturally gets dark trim and headlights, a unique spoiler and quad tailpipes to distinguish it as a V. Under the hood is a turbocharged 2.7-liter four-cylinder that is based on the engine in the new Chevy Silverado. It makes 320 horsepower and 369 pound-feet of torque, a far cry from the ATS-V's 464 horsepower and 445 pound-feet of torque. Cadillac CT4-V View 12 Photos Power goes through a 10-speed automatic transmission only. Both rear-wheel drive and all-wheel drive are available. It gets a mechanical limited-slip differential whereas the ATS-V had an electronically controlled limited-slip differential a la Camaro ZL1. The brakes have four-piston calipers at each corner versus six-piston front units and four-piston rear units on the ATS-V, and the rotors are smaller. Magnetic Ride Control remains standard on the rear-drive version, but the all-wheel-driver version sticks with conventional shocks. The new CT4-V is about 200 pounds lighter than the ATS-V, though, and it has 50/50 weight distribution. Additionally, both the CT4-V and the CT5-V have Super Cruise available as an option. Moving on to the CT5-V, it looks like a regular CT5 but with dark trim and lights, quad tailpipes and a unique rear diffuser. Instead of the CTS-V's 640-horsepower supercharged V8, the CT5-V uses a twin-turbo 3.0-liter V6 making 355 horsepower and 400 pound-feet of torque. Changes made to the 3.0 for the CT5-V include a new intake system and new exhaust, and it revs higher too. Like the CT4-V, it comes with a 10-speed automatic and either rear-wheel drive or all-wheel drive. It does get the electronically controlled limited-slip differential.
